ApostropheCMS: Import archives can exhaust server storage and deny service

ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.1 of the import-export module, an authenticated importer can submit archives whose decompressed bytes, entry count, and entry sizes are not bounded before document-type authorization, and extraction or parsing failures can leave staging and extracted artifacts without unconditional cleanup. The already-hardened pre-authentication and write-error paths are separate, and current end-to-end denial-of-service impact from this residual path remains subject to maintainer validation. This issue is fixed in version 3.7.1.
